And, the 4th port 23k of the oil circuit footpath Lf of wheel system before the shell 23a of master cylinder 23 is provided with and is used to be communicated with the 3rd port 23j of the 1st hydraulic pressure chamber 23d and the oil circuit footpath Lr that constitutes the back wheel system and is used to be communicated with the 2nd hydraulic pressure chamber 23f and formation.As shown in Figure 4, oil circuit footpath Lr is communicated with the 1st hydraulic pressure chamber 23d respectively with left and right sides trailing wheel RL, the wheel cylinder WC3 of RR, WC4, and oil circuit footpath Lf is communicated with the 2nd hydraulic pressure chamber 23f and left and right sides front-wheel FL, the wheel cylinder WC1 of FR, WC2 respectively.
If each wheel cylinder WC1, WC2, WC3, WC4 are supplied to hydraulic pressure (basic hydraulic pressure, modulated pressure) through oil circuit footpath Lf, Lr from master cylinder 23; Each brake equipment BK1, BK2, BK3, BK4 action that corresponding each wheel cylinder WC1, WC2, WC3, WC4 are provided with are respectively given hydraulic braking force (basic hydraulic braking force, brake fluid pressure braking force) to each wheel FL, FR, RL, RR.As each brake equipment BK1, BK2, BK3, BK4, disc type brake, drum brake etc. are arranged, the rotation of the discal rotor of brake plate, restriction such as friction means such as braking skin etc. and wheel one, brake wheel etc.
Particularly; As shown in Figure 3, joystick 26 has operating effort transmission mechanism 70, and this operating effort transmission mechanism 70 constitutes; During till braking operation state is in from initial state under stepping on to specified states; The operating effort that will not be imparted to brake pedal 21 passes to the 1st piston 23b of master cylinder 23, after specified states, the operating effort that is imparted to brake pedal 21 is passed to the 1st piston 23b of master cylinder 23.This operating effort transmission mechanism 70 is the connect mechanisms that can the 1st piston 23b of brake pedal 21 and master cylinder 23 be linked linkedly.
Operating effort transmission mechanism 70 is arranged at, constitute joystick 26 brake pedal 21 side sections that is the 1st joystick 26a (the 1st bar), with junction surface as the 2nd joystick 26b (the 2nd bar) of master cylinder 23 side sections.Particularly, the end of the 1st joystick 26a is connected with brake pedal 21.Form tube portion 71 (outer side tube parts) in the other end of the 1st joystick 26a (leading section).Tube portion 71 forms the bottom tube-like that has of front opening.The other end of the 2nd joystick 26b is connected with master cylinder 23 (the 1st piston 23b) through push rod 27 grades.In the end of the 2nd joystick 26b (leading section), be formed with in tube portion 71 the tubular engagement section 72 (inboard cylinder portion) that crank motion ground is slidably taken in.Tubular engagement section 72 can not be extracted from tube portion 71.And, between tube portion 71 and tubular engagement section 72, take in the spring 73 of the oriented direction that two bar 26a, 26b are separated along vibration-direction (direction that the volume of the inner space 75 increases) application of force.This operating effort transmission mechanism 70 is that basic hydraulic braking force produces restraint device.
Between the leading section of the leading section of the 1st joystick 26a and the 2nd joystick 26b, promptly between tube portion 71 and tubular engagement section 72, form the inner space 75 that is full of with fluid (being air in this embodiment).The volume of inner space 75 changes with respect to relatively moving of tube portion 71 according to tubular engagement section 72.As fluid, not only can be gas, also liquid can be arranged.
Thereby the access 74 that has the fluid inflow and outflow in the inside and outside confession inner space 75 that is communicated with inner space 75 in the operating effort transmission mechanism 70.Access 74, the limit fluid outflow in space 75 does not internally limit when non-urgency is stepped on when the urgency of brake pedal 21 is stepped on.Access 74 is cutoff port (orifice).This cutoff port is the gap of tubular engagement section 72 of tube portion 71 and the 2nd joystick 26b of the 1st joystick 26a.And, fast when speed is stepped on than non-urgency under the stepping on when suddenly stepping on.
Action to the hydraulic brake system B of binding parts with formation like this describes.At first; Do not step on down and master cylinder presses (basic hydraulic pressure) not form at brake pedal 21; And brake actuator 25 does not move and under the inchoate situation of brake fluid pressure, operating effort transmission mechanism 70 is the state of Fig. 3, and joystick 26 is owing to the application of force of spring 73 becomes extreme length.
When brake pedal 21 non-urgency were stepped on, fluid did not receive access 74 restrictions from the outflow of the inner space 75 of operating effort transmission mechanism 70.At this moment, the volume of inner space 75 diminishes, but the air in the inner space 75 is compressed hardly.Thereby, be the state that the 2nd joystick 26b slides on the 1st joystick 26a, up to the 1st joystick 26a and the direct butt of the 2nd joystick 26b, the 2nd joystick 26b is just pushed.
And the state that so-called the 2nd joystick 26b slides on the 1st joystick 26a is meant that the 1st joystick 26a slides as this embodiment, being on the 2nd joystick 26b that stops.
That is, if brake pedal 21 non-urgency are stepped on, then according to operating effort, the application of force of the 1st joystick 26a antagonistic spring 73 moves to the direction of the 2nd joystick 26b.At this moment, because that the application of force of spring 73 is set at than makes each application of force of spring 23e, 23g of resetting spring and the master cylinder 23 of the negative pressure type booster 22 that the 2nd joystick 26b restores is little, though therefore spring 73 is compressed the 2nd joystick 26b and does not move.That is, form the master cylinder pressure, do not press so do not give master cylinder to wheel cylinder WC1, WC2, WC3, WC4 owing to limited at master cylinder 23.
And; The leading section of the tubular engagement section 72 if brake pedal 21 is stepped on play in the tube portion 71 and the bottom butt (the perhaps stage portion butt of an end face of tube portion 71 and tubular engagement section 72) of tube portion 71 then pass through operating effort thereafter and the 2nd joystick 26b is mobile with the 1st joystick 26a.That is, begin to form master cylinder at master cylinder 23 and press, by the stepping on of brake pedal 21 under and the master cylinder of generation is pressed to wheel cylinder WC1, WC2, WC3, WC4 and given.And if be disengaged under the stepping on of brake pedal 21, then operating effort transmission mechanism 70 turns back to the state of Fig. 3 through the application of force of spring 73.
The basic hydraulic pressure that is formed by this hydraulic brake system B and the basic hydraulic braking force brought are represented with the dotted line of Fig. 5.Promptly; Be positioned at from stepping on the starting position to play under the situation between the position (butt position) of the 1st joystick 26a and the 2nd joystick 26b butt at brake-pedal travel; Because the basic hydraulic pressure that the 1st and the 2nd hydraulic pressure chamber 23d of master cylinder 23,23f produce is restricted to 0, so the generation of basic hydraulic braking force also is restricted to 0.And; Be positioned at brake-pedal travel under the situation of position of the position that surpasses the 1st joystick 26a and the 2nd joystick 26b butt; The generation restriction of aforesaid basic hydraulic pressure is disengaged; The basic hydraulic pressure that the 1st and the 2nd hydraulic pressure chamber 23d, 23f produce is corresponding with brake-pedal travel, and therefore basic hydraulic braking force is also corresponding with brake-pedal travel.And the state that the 1st joystick 26a is positioned at the position of the 2nd joystick 26b butt is a specified states, is that basic hydraulic braking force begins and the cooresponding braking operation state that boosts of brake-pedal travel.Thereby, of the dotted line of Fig. 5, the basal liquid straightening connect give wheel cylinder WC1, WC2, WC3, WC4, said each wheel FL, FR, RL, RR are produced and the cooresponding basic hydraulic braking force of basic hydraulic pressure.
And specified states begins and the cooresponding braking operation state that boosts of braking operation state for the generation of basic hydraulic braking force restriction is disengaged basic hydraulic braking force.And, from stepping on down distance that is the predetermined distance s of starting position till the butt position (with s synonym shown in Figure 3.) regenerative braking device A produces the maximum regeneration braking force when being preferably set at braking operation state and being specified states.Thus, when braking operation state became specified states, restriction and regenerative braking device A that master cylinder 23 is removed the generation of basic hydraulic braking force produced the maximum regeneration braking force.Wherein, s shown in Figure 3 is the distance of the stage portion of the tubular engagement section 72 of end face of the tube portion 71 of the 1st joystick 26a in not stepping on the push rod 26 of state down and the 2nd joystick 26b.
In addition, under the situation of anxious brake-apply 21, fluid receives access 74 restrictions from the outflow of the inner space 75 of operating effort transmission mechanism 70.At this moment, for example in inner space 75, form pressurized air, before direct butt the 2nd joystick 26b of the 1st joystick 26a, the 1st joystick 26a pushes the 2nd joystick 26b and push rod 27 through pressurized air thus.Therefore, become the state that the 2nd joystick 26b moves with the 1st joystick 26a, thereby therefore push the 1st piston 23b with the 1st port 23h shutoff, thereby produce basic hydraulic pressure at the 1st hydraulic pressure chamber 23d through push rod 27.That is, basic hydraulic braking force produce restraint device the 1st joystick 26a be in from step on till the butt position is played in the starting position down during produce basic hydraulic braking force.Thus, if the anxious brake-apply 21 of driver can actively produce basal liquid village braking force in the time of then between the 1st joystick 26a is till the butt position is played in the starting position under stepping on.
And the 2nd joystick 26b is meant before the 1st joystick 26a and the direct butt of the 2nd joystick 26b with the state that the 1st joystick 26a moves, the state that two bar 26a, 26b move together.
And, during this through with the coordination that is used to reach with the hydraulic brake system B of the cooresponding car brakeing power of braking operation state, regenerative braking device A utilizes regenerative brake power to replenish basic hydraulic braking force in shortage with respect to car brakeing power.Thereby, be in from step on the low legpower zone till the butt position, following starting position at the 1st joystick 26a, can when the urgency of brake pedal 21 is stepped on, have precedence over high regeneration efficiency, high gas consumption rate, and realize giving in early days of basic hydraulic braking force.
The basic hydraulic pressure that is formed by this hydraulic brake system B and the basic hydraulic braking force brought are represented with the solid line of Fig. 5.That is, brake-pedal travel is positioned at from stepping on down the starting position and plays under the situation with the position between till the locked position of coupler (port locked position of coupler) of the 1st port 23h complete atresia, and the generation of basic hydraulic pressure is not limited and produces according to pedal stroke.And; Be positioned at brake-pedal travel under the situation till the position (butt position) of playing the 1st joystick 26a and the 2nd joystick 26b butt from locked position of coupler; Because the 1st port 23h complete atresia; Further increase (increase increase) so basal liquid is pressed, therefore produce bigger basic hydraulic pressure.And, being positioned under the situation above the position of butt position at brake-pedal travel, the basic hydraulic pressure that the 1st and the 2nd hydraulic pressure chamber 23d, 23f produce is corresponding with brake-pedal travel, so basic hydraulic braking force is also corresponding with brake-pedal travel.
And in this embodiment, the port locked position of coupler is set to be stepped between following starting position and the butt position.And the port locked position of coupler also can be set in the position above the butt position.
And the trend of the basal liquid village braking force when basic hydraulic braking force when suddenly stepping on and non-urgency are stepped on depends on the characteristic of master cylinder 23, negative pressure type booster 22 to have same characteristic.And, owing to pushed, so Zao when the rising of the basic hydraulic braking force during anxious stepping on is stepped on than non-urgency constantly from stepping on the following zero hour the 1st piston 23b.
Below, with reference to Fig. 4 brake actuator 25 is elaborated.This brake actuator 25 is generally well-known, is fluid control valve 31,41, the supercharger control valve 32,33,42,43 that constitutes abs control valve and pressure reduction control valve 35,36,45,46, pressure regulation receiver 34,44, pump 37,47, motor M etc. are assembled in the housing and constitute.
At first, the formation to the preceding wheel system of brake actuator 25 describes.Has the fluid control valve 31 that constitutes by differential pressure control valve on the Lf of oil circuit footpath.This fluid control valve 31 is braked ECU60 control and between connected state and differential pressure state, switches.Fluid control valve 31 is in connected state usually, but can be through being made as the differential pressure state Lf2 keeps exceeding than the oil circuit footpath Lf1 of master cylinder 23 sides the pressure of regulation differential pressure amount in the oil circuit footpath of wheel cylinder WC1, WC2 side.This differential pressure is through braking ECU60 according to control current and by pressure regulation.
Oil circuit footpath Lf2 is divided into 2 shunt; Have when the boost mode of ABS control the supercharger control valve 32 that the supercharging of the brake fluid pressure that flows to wheel cylinder WC1 is controlled in shunt, another has when the boost mode of ABS control the supercharger control valve 33 that the supercharging of the brake fluid pressure that flows to wheel cylinder WC2 is controlled on along separate routes.These supercharger control valves 32,33 constitute the two-position valve that can control connection, off-state through braking ECU60.And, when these supercharger control valves 32,33 are controlled as connected state, can be with the basic hydraulic pressure of master cylinder 23 or/and be applied to each wheel cylinder WC1, WC2 by the driving of pump 37 and the formed modulated pressure of control of fluid control valve 31.And supercharger control valve 32,33 can be carried out ABS control with pressure reduction control valve 35,36 and pump 37.
And, do not carrying out the common glancing impact of ABS control, these supercharger control valves 32,33 are controlled as normal connected state.And, be provided with safety valve 32a, 33a on the supercharger control valve 32,33 respectively side by side, when when ABS control, leaving brake pedal 21, turn back to petrol storage tank 24 from the braking liquid of wheel cylinder WC1, WC2 side together with it.
And the oil circuit footpath Lf2 between supercharger control valve 32,33 and each wheel cylinder WC1, WC2 is communicated in pressure regulation receiver 34 through oil circuit footpath Lf3.Being equipped with respectively among the Lf3 of oil circuit footpath can be through the pressure reduction control valve 35,36 of braking ECU60 control connection, off-state.These pressure reduction control valves 35,36 are opened state for normal off under common braking mode (during the non-action of ABS); And; Be made as suitable connected state; Come to bleed off braking liquid to pressure regulation receiver 34, thereby can control the brake fluid pressure among wheel cylinder WC1, the WC2, prevent that wheel from reaching the locking tendency through oil circuit footpath Lf3.
And, dispose pump 37 and safety valve 37a will being in the oil circuit footpath Lf4 that fluid control valve 31 and supercharger control valve 32, oil circuit footpath Lf2 and pressure regulation receiver 34 between 33 couple together.And, pressure regulation receiver 34 and master cylinder 23 ways of connecting are provided with oil circuit footpath Lf5 through oil circuit footpath Lf1.Pump 37 is driven by motor M according to the instruction of braking ECU60.Pump 37 is when the pressure reducing mode of ABS control, and the braking liquid that stores in braking liquid in suction wheel cylinder WC1, the WC2 or the pressure regulation receiver 34 turns back to master cylinder 23 through the fluid control valve 31 that is in connected state.And; Pump 37 is when being formed for the modulated pressure of control vehicle stable postures such as VSC control, traction control, auxiliary braking; Can make the fluid control valve 31 that switches to the differential pressure state produce differential pressure; The braking liquid that sucks in the master cylinders 23 through oil circuit footpath Lf1, Lf5 and pressure regulation receiver 34 spues to each wheel cylinder WC1, WC2 through oil circuit footpath Lf4, Lf2 and the supercharger control valve 32,33 that is in connected state and to give modulated pressure.And in order to relax the pulsation of the braking liquid that pump 37 spues, the upstream side of the pump 37 of Lf4 is equipped with pressure accumulator 38 in the oil circuit footpath.
And, in the Lf1 of oil circuit footpath, being provided with compress into the pressure sensor P that row detects as the master cylinder of master cylinder 23 inside brake hydraulic pressure, this detection signal is sent to braking ECU60.And pressure sensor P can be arranged among the Lr1 of oil circuit footpath.
And, the back wheel system of brake actuator 25 be with aforementioned before the same structure of wheel system and oil circuit footpath Lf likewise, the oil circuit footpath Lr that constitutes the back wheel system is made up of oil circuit footpath Lr1 ~ Lr5.Have among the Lr of oil circuit footpath and same fluid control valve 41 of fluid control valve 31 and and the same pressure regulation receiver 44 of pressure regulation receiver 34.Have the supercharger control valve 42,43 same among the oil circuit of the fork that is communicated with wheel cylinder WC3, WC4 footpath Lr2, the Lr2, have the pressure reduction control valve 45,46 same among the Lr3 of oil circuit footpath with pressure reduction control valve 35,36 with supercharger control valve 32,33.Have pump 47, safety valve 47a and the pressure accumulator 48 same among the Lr4 of oil circuit footpath with pump 37, safety valve 37a and pressure accumulator 38.And, be set side by side with respectively on the supercharger control valve 42,43 and safety valve 32a, same safety valve 42a, the 43a of 33a.
Thus; The modulated pressure that will be formed by the control of the driving of pump 37,47 and fluid control valve 31,41 is imparted to each wheel FL, FR, RL, the wheel cylinder WC1 of RR, WC2, WC3, WC4, can produce the modulated pressure braking force at wheel FL, FR, RL, RR whereby.
And; Braking device for vehicle; As shown in Figure 1, mainly have pedal stroke sensor 21a, respectively detect the wheel velocity of each wheel FL, FR, RL, RR each wheel speed sensors Sfl, Sfr, Srl, Srr, pressure sensor P, each control cock 31,32,33,35,36,41,42,43,45,46, with motor M bonded assembly braking ECU (electronic control unit) 60.The detection that braking ECU60 gets based on utilizing these each sensors and the state of Gear-shift switch; Control switch hydraulic brake system B each control cock 31,32,33,35,36,41,42,43,45,46 state or carry out electrical current control, control is given the modulated pressure of wheel cylinder WC1 ~ WC4, is promptly given the modulated pressure braking force of each wheel FL, FR, RL, RR.
And, braking ECU60 can be each other communicatedly with mix moving ECU19 and be connected, carry out the regenerative brake that motor 12 carried out and the co-operative control of oil brake, be equal to reach the vehicle that full application of brake power with vehicle is merely oil brake.Particularly, be braking operation state with respect to driver's brake request, the regeneration required value of the amount that braking ECU60 bears as regenerative braking device in mixing moving ECU19 output full application of brake power is the object regeneration braking force as the expected value of regenerative braking device.Mix moving ECU19 based on the regeneration required value of being imported (object regeneration braking force); Considering derives actual actual reproduction execution value as regeneration braking effect after the speed of a motor vehicle, the battery charging state etc.; Be worth cooresponding regenerative brake power through inverter 16 control motors 12 to produce, and the actual reproduction execution value that derives is exported to braking ECU60 with said actual reproduction execution.
And; To wheel cylinder WC1, WC2, WC3, when WC4 has supplied with basic hydraulic pressure; Braking ECU60 processes mapping graph, form exclusive disjunction formula with the basic hydraulic braking force that brake equipment BK1, BK2, BK3, BK4 are imparted to wheel FL, FR, RL, RR, stores in the memory device in advance.And braking ECU60 processes mapping graph, form exclusive disjunction formula according to giving to the object regeneration braking force of wheel FL, FR, RL, RR as the braking operation state of the stroke (or master cylinder pressure) of brake pedal, stores in the memory device in advance.And, store co-operative control program shown in Figure 6 (vehicle is used the control of braking program) among the braking ECU60.
Below, describe along the action of the diagram of circuit of Fig. 6 the braking device for vehicle that as above constitutes.For example at the ignition lock of vehicle (diagram is omitted) when be opening, every short time at a distance from regulation of braking ECU60 just carries out and the cooresponding program of above-mentioned diagram of circuit.Braking ECU60 is from the pedal stroke (step 102) of pedal stroke sensor 21a input as the serviceability of brake pedal 21, the cooresponding object regeneration braking force of pedal stroke (step 104) of calculating Yu being imported.At this moment, to use the expression pedal stroke of storage in advance be braking operation state and mapping graph, the form exclusive disjunction formula of the relation of the object regeneration braking force of giving to wheel FL, FR, RL, RR to braking ECU60.
The object regeneration braking force is calculated step 104 the object regeneration braking force of gained and is exported to mixed moving ECU19, and brake actuator 25 is not controlled (step 106,108) greater than under 0 the situation.Thereby, being stepped on following time and afore-mentioned likewise at brake pedal 21, hydraulic brake system B only gives basic hydraulic braking force (static pressure braking) to wheel FL, FR, RL, RR.And; Mix the regeneration required value of moving ECU19 input expression object regeneration braking force; Consider after speed of a motor vehicle, the battery charging state etc. through inverter 16 control motors 12 producing regenerative brake power based on this value, and actual reproduction execution value is exported to braking ECU60.Therefore, carrying out brake operating, and the object regeneration braking force is greater than under 0 the situation, basic hydraulic braking force is added regenerative brake power and is imparted into wheel FL, FR, RL, RR.Carry out the regeneration co-operative control like this, but this moment basic hydraulic braking force and regenerative brake power corresponding with brake operation force, so the one of which example is shown in Fig. 5.Brake operation force when regenerating co-operative control has been shown among Fig. 5 and has represented basic hydraulic braking force and the correlationship of the braking force of the summation of regenerative brake power.
Promptly; Master cylinder 23 (basic hydraulic braking force generation restraint device) according to this 1st embodiment; When the non-urgency of brake pedal 21 is stepped on; Be in from braking operation state initial state under the stepping on of the state of stepping on the following zero hour play till the specified states during so that the mode that basic hydraulic braking force is in below the specified value limits its generation.Thus; If the driver steps on down brake pedal 21, then shown in the dotted line of Fig. 5, from step on down initial state till the specified states during; The basis hydraulic braking force is forced and is limited in below the specified value, thereby corresponding during this period braking operation state is only given regenerative brake power.And, become at braking operation state under the situation of specified states, remove the generation restriction of basic hydraulic braking force, and regenerative braking device A generation maximum regeneration braking force, therefore only give the maximum regeneration braking force.And; Braking operation state becomes under the situation of the state stepped on down from specified states; Keeping the releasing of the generation restriction of basic hydraulic braking force, make hydraulic brake system B and regenerative braking device A coordination, (is the maximum regeneration braking force based on basic hydraulic braking force and regenerative brake power basically.) give and the cooresponding car brakeing power of braking operation state.
In addition, when the urgency of brake pedal 21 is stepped on, do not limit the generation of basic hydraulic braking force, shown in the solid line of Fig. 5, just give basic hydraulic braking force the following zero hour from stepping on.
Braking ECU60 detects the change (step 110 ~ 114) by the regenerative brake power of the actual generation of regenerative braking device A.Particularly; With respect to step 104 calculate and the object regeneration braking force; The actual actual reproduction execution value (step 110) of giving the actual reproduction braking force of wheel FL, FR, RL, RR of braking ECU60 input expression regenerative braking device A; Calculate poor (step 112) of the actual reproduction braking force of object regeneration braking force that step 104 calculates and step 110 input,, then detect regenerative brake power and changed (step 114) if this difference of calculating is bigger than specified value a.
And; If detect the change of regenerative brake power; Brake ECU60 so and be judged to be " being " in step 114; Pump 37,47 and modulated pressure control cock 31,41 through driving hydraulic brake system B form modulated pressure, give the modulated pressure braking force based on modulated pressure to wheel FL, FR, RL, RR, and compensation is because the caused braking force of the change of above-mentioned detected regenerative brake power not enough (step 116) thus.Particularly, braking ECU60 control modulated pressure is to form the object regeneration braking force of calculating with step 104 and at the cooresponding hydraulic pressure of difference poor, that promptly calculate in step 112 of the actual reproduction braking force of step 110 input.Thereby braking ECU60 Starting motor M driving pump 37,47 applies electric current to the linear solenoid valve of differential pressure control valve 31,41, so that the hydraulic pressure of the braking liquid of supplying with to wheel cylinder WC1, WC2, WC3, WC4 from pump 37,47 becomes modulated pressure.At this moment, further preferred linear solenoid valve 33 is by controlled reset, so that the hydraulic pressure of the wheel cylinder WC1 that hydraulic pressure transducer 40 detects, WC2, WC3, WC4 becomes modulated pressure.In addition, under the situation of the change that does not detect regenerative brake power, braking ECU60 is judged to be " denying " in step 114, stop the control (step 118) of brake actuator 25.
As above state clearly,, when the non-urgency of brake pedal 21 is stepped on, do not receive access 74 restrictions from the outflow of the fluid of the inner space 75 of the operating effort transmission mechanism 70 that forms at joystick 26 according to this 1st embodiment.At this moment; Though the volume of inner space 75 diminishes; But the fluid in the inner space 75 is compressed hardly, therefore is in the 2nd joystick 26b (the 2nd bar) and goes up the state that slides at the 1st joystick 26a (the 1st bar), in the generation of this state limit basis hydraulic braking force.Thus, under the situation of the anxious brake-apply 21 of driver, particularly be in from stepping on following starting position under the situation the butt position at the 1st joystick 26a, basic hydraulic braking force is forced and is limited in below the specified value.And, during this period through with the coordination that is used to reach with the hydraulic brake system B of the cooresponding car brakeing power of braking operation state, regenerative braking device A utilizes regenerative brake power to replenish basic hydraulic braking force in shortage with respect to said car brakeing power.Thereby, under the situation of the anxious brake-apply 21 of driver, particularly be in from step on the low legpower zone till the butt position, starting position down at the 1st joystick 26a, can be through actively utilizing regenerative brake power to reach high regeneration efficiency, being high gas consumption rate.
In addition, when anxious brake-apply 21, the fluid outflow in space 75 internally receives access 74 restrictions.At this moment, for example in inner space 75, form pressurized air, before direct butt the 2nd joystick 26b of the 1st joystick 26a, the 1st joystick 26a pushes the 2nd bar through pressurized air thus.Therefore, be the state that the 2nd joystick 26b moves with the 1st joystick 26a, the generation of under this state, removing basic hydraulic braking force suppresses.That is, operating effort transmission mechanism 70 (basic hydraulic braking force generation restraint device) the 1st joystick 26a be in from step on following starting position till the butt position during produce basic hydraulic braking force.Thus, under the situation of the anxious brake-apply 21 of driver, can the 1st joystick 26a be in from step on starting position down till the butt position during the time actively produce basic hydraulic braking force.And, during this period through with the coordination that is used to reach with the hydraulic brake system B of the cooresponding car brakeing power of braking operation state, regenerative braking device A utilizes regenerative brake power to replenish basic hydraulic braking force in shortage with respect to said car brakeing power.Thereby, be in from step on the low legpower zone till the butt position is played in following starting position at the 1st joystick 26a, when the urgency of brake pedal 21 is stepped on, have precedence over high regeneration efficiency, high gas consumption rate, realize giving in early days of basic hydraulic braking force.
As stated; In braking device for vehicle; Brake pedal 21 from step on the low legpower zone of playing the following zero hour till becoming specified states, when non-urgency is stepped on,, reach high regeneration efficiency, high gas consumption rate through actively utilizing regenerative brake power; And when anxious stepping on, give basic hydraulic braking force as much as possible in early days, can realize that the two gets both.
And access 74 is a cutoff port.Thereby, can carry out throttling with the outflow in space 7 internally of simple structure convection cell.
And cutoff port is the gap 74 of the 1st joystick 26a and the 2nd joystick 26b.Thereby, can carry out throttling with simple structure and the outflow in space 7 internally of low-cost convection cell.
In addition; At least one side of the leading section of the leading section of the 1st joystick 26a and the 2nd joystick 26b has the tube portion 71 that bottom tube-like is arranged of forward end opening; The opposing party slides in tube portion 71, and inner space 75 is formed at the inboard of outer side tube part 71 and inboard cylinder portion 72.When stepping on, the urgency that thus, can utilize easy and simple structure to be implemented in brake pedal 21 in inner space 75, forms pressurized air.
And; When the non-urgency of brake pedal 21 is stepped on, under the stepping on of brake pedal 21, begin till the bottom of the said tube of leading section butt portion 71 of the tubular engagement section 72 in the tube portion 71 during, the 2nd joystick 26b slides on the 1st joystick 26a; Limit the generation of basic hydraulic braking force; On the other hand, when the urgency of brake pedal 21 is stepped on, begin the bottom of the said tube of leading section butt portion 71 of the tubular engagement section 72 in the portion of playing 71 under the stepping on of brake pedal 21 before; The 1st joystick 26a pushes the 2nd joystick 26b through the fluid of compression in the inner space 75, removes the generation restriction of basic hydraulic braking force.Thereby; During till the bottom of the said tube of the leading section butt portion 71 that under the stepping on of brake pedal 21, begins the tubular engagement section 72 in the tube portion 71 in the promptly low legpower zone; When the non-urgency of brake pedal 21 is stepped on, can be through actively utilizing regenerative brake power to reach high regeneration efficiency, being high gas consumption rate.On the other hand, when the urgency of brake pedal 21 is stepped on, have precedence over high regeneration efficiency, high gas consumption rate, realize giving in early days of basic hydraulic braking force.
And, the brake pedal 21 of the leading section of the tubular engagement section 72 in the tube portion 71 and the bottom butt of said tube portion 71 step on upper/lower positions, the maximum regeneration braking force setting that can produce based on regenerative braking device A.Thus; When the non-urgency of brake pedal 21 is stepped on; When brake-pedal travel is positioned at the position that surpasses said butt position; The maximum regeneration braking force that can utilize basic hydraulic braking force that hydraulic brake system B produced and regenerative braking device A to be produced is given and the cooresponding car brakeing power of the serviceability of brake pedal to vehicle, can realize high regeneration efficiency.
And in above-mentioned the 1st embodiment, the main-cylinder stroke sensor 23z of the stroke that braking operation state can be through detecting master cylinder 23 detects.
2) the 2nd embodiment
Below, with reference to accompanying drawing the 2nd embodiment that hybrid vehicle is suitable for braking device for vehicle of the present invention is described.The negative pressure type booster 22 of above-mentioned hydraulic brake system B does not have complemental brake system, but has complemental brake system in the negative pressure type booster 122 of the hydraulic brake system B of this 2nd embodiment.Complemental brake system is an auxiliary little legpower and form the device that big braking force is given.
Among Fig. 7, negative pressure type booster 122 has shell 81, and this shell 81 is made up of the place ahead lid 81a, rear lid 81b and movable wall 82, and inside is divided into level pressure chamber R1 and transformation chamber R2 by movable wall 82.Movable wall 82 in the shell 81 is made up of the barrier film 82b of metal plate 82a and rubber system, but opposite shell 81 fore-and-aft directions are provided with movably.
Level pressure chamber R1 is communicated with engine intake manifold (not shown) as negative pressure source, total negative pressure that keeps in the driving engine action.Transformation chamber R2 is communicated with, breaks off with level pressure chamber R1 through path 83 and valve system 84, and through valve system 84 also with atmosphere, disconnection.
As shown in Figure 8; In the negative pressure type booster 122; When the urgency of brake pedal 21 is stepped under the driver steps in alarm; If joystick 26 is bigger than specified value A with the rate of travel of power piston 85, the tapered portion 87a butt of the inclined plane part 86b of plunger 86 and holding member 87 then makes by endless elastomeric 88 to the holding member 87 of the undergauge direction application of force in the radial direction hole enlargement.
If the 87a1 of minimum diameter portion of tapered portion 87a climbs up on the stage portion 86d of plunger 86, the 89c of the portion that is stuck of valve base part 89 is disengaged with the engaging of engagement section 87b of holding member 87 so.Because valve base part 89 is by spring 91 application of force rearward, after the engaging that is stuck the 89c of portion was removed, valve base part 89 rearward moved because of the application of force of spring 91 immediately.
If valve base part 89 rearward moves, the valve 93a butt of the 2nd negative pressure valve seat 92 of valve base part 89 and the movable part 93 that constitutes valve system 84 so breaks off being communicated with of level pressure chamber R1 and transformation chamber R2.At this moment; During plunger 86 is in and forwards moves integratedly with joystick 26; Because valve base part 89 rearward pushes back the movable part 93 of valve system 84, so the valve 93b of the atmospheric valve seat 86a of plunger 86 and the movable part 93 that constitutes valve system 84 separates transformation chamber R2 and atmosphere rapidly.Its result; Compare with common braking maneuver; Level pressure chamber R1 and transformation chamber R2 be communicated with disconnection and transformation chamber R2 carried out with being communicated with more rapidly of atmosphere; And in fact enlarged the distance towards the bearing surface 85d and the atmospheric valve seat 86a of counter-force parts 94 towards the distance of the bearing surface 85d of counter-force parts 94 and the 1st negative pressure valve seat 95 and power piston 85 of power piston 85, the output under the state of beating is bigger than common state.
The emergency braking characteristic of the negative pressure type booster of this embodiment is through changing bouncing characteristic, output block is applied the propulsive force bigger than common glancing impact reaching.For bouncing characteristic is changed, in Fig. 8, can increase the gap B of butt parts 96 and counter-force parts 94.The expansion of gap B, identical with the distance that enlarges power piston 85 towards the bearing surface 85d of counter-force parts 94 and atmospheric valve seat 86a towards the distance of the bearing surface 85d of counter-force parts 94 and the 1st negative pressure valve seat 95 and power piston 85.Promptly; Through rearward being moved, negative pressure valve seat 38 and atmospheric valve seat 86a enlarge gap B; Make butt parts 96 become big, make output bigger than common state with respect to the beat output of state of the infinitely-great what is called of ratio of input from the output that counter-force parts 94 receive till the counter-force.
Fig. 9 shows common braking characteristics and above-mentioned emergency braking characteristic.Among Fig. 9, beating of glancing impact can only obtain the output of F1 size usually, and beating during emergency braking increases to F2, just can produce very big brake fluid pressure through little pedal force.
And, in the negative pressure type booster of this 2nd embodiment, the 1st joystick 26a be in from step on till the butt position is played in the starting position down during, the beginning auxiliary braking.
As above state bright institute and show clearly, according to this 2nd embodiment, when the non-urgency of brake pedal 21 was stepped on, fluid did not receive access 74 restrictions from the outflow of the inner space 75 of the operating effort transmission mechanism 70 of joystick 26 formation.Therefore, can access effect, the effect same with above-mentioned the 1st embodiment.
In addition, under the situation of anxious brake-apply 21, fluid receives access 74 restrictions from the outflow of the inner space 75 of operating effort transmission mechanism 70.Therefore, in inner space 75, form pressurized air, before the 1st joystick 26a and the direct butt of the 2nd joystick 26b, the 1st joystick 26a pushes the 2nd joystick 26b and push rod 27 through pressurized air thus.Thereby, through push rod 27 pushing the 1st piston 23b that the 1st port 23h is inaccessible, produce basic hydraulic pressure at the 1st hydraulic pressure chamber 23d thus.That is, the 1st joystick 26a be in from step on following starting position till the butt position during, basic hydraulic braking force produces restraint device and produces basic hydraulic braking force.That is, be the state that the 2nd joystick 26b moves with the 1st joystick 26a.Thus, if the anxious brake-apply 21 of driver, then the 1st joystick 26a be positioned at from step on starting position down till the butt position during, can produce basic hydraulic braking force energetically.
